I have a compaq presario patop 2500. The AC/DC receptor plug in back of unit heated up and broke.
The laptop fine through with battery, but i want to be able to plug it in, obviously. I want to hardwire the ac/dc adaptor directly to the 5 pin plug inside the battery pack (by going through an old battery pack that I emptied out- I took all the old cells and circuitry out)
Does anyone know if its just positive to positive, and negative to negative?
